Title: Filling nozzle and installation for filling drums with liquid yellow phosphorus
IPC: B67C3/34
Filed: 1972-08-03
Abstract: 1374314 Filling with liquid phosphorous KNAPSACK AG 3 Aug 1972 [18 Aug 1971] 36299/72 Headings B8T and B8C The installation and nozzle described are for filling drums with liquid yellow phosphorous which must be kept above its melting point (45‹ C.) and under water.  Nozzle.-The filling nozzle (Fig. 1) comprises an outer heating jacket 6, with a warm water inlet 4 and an outlet 5, enclosing the annular space 16 down which the phosphorous flows from tube 3, a nozzle supporting tube 8 which is fed with warm water from tube 15 and, enclosed by the tube 8 and communicating with it through holes 33, the control pipe 23 which is attached at its upper end by an eye 26 to a plate 54 which can be raised by a cylinder 56 against springs 53. The pipe 23 is screwed to the control piston 17 which has a spring-loaded outlet valve 21. At the bottom of the tube 8 is attached a control cylinder 11 which is welded via a conical piece 12 to the inner wall 1 of the jacket 6. A gland comprising a two-piece packing 18 with a central apertured spacer ring 20 provides the seal between the cylinder 11 and piston 17 and a similar gland 34, 35 is provided at the top of the tube 8. The whole filling nozzle is mounted on a carriage 39 which is raised and lowered by cylinders 40. Machine.-The drums are arranged two-deep in a semicircle and the nozzle is swung over them on a frame 36 (Fig. 5). The upper ends of the cylinders 40 are attached to a trolley 38 which is moved along the top of the frame 36 by a cylinder 37.  Operation.-The cylinders 40 lower the nozzle into the drum, which previously has been filled for a preset time with warm water from a pipe 52 until a cross-shaped member 47, resiliently mounted on the drum cover 44 that the nozzle carries, contacts the drum whereupon pins 46 arranged on the member 47 actuate switches carried on the cover 44 stopping the descent. Warm water is discharged from the heating jacket 6 through the outlet 5 and regulating valve 49 and from tube 15 via holes 33 and valve 21 into the drum until the water reaches the required level when a water level indicating probe carried on the member 47 gives a signal causing the cylinder 56 to raise the control piston 17 allowing the phosphorous to flow out of the space 16. When the phosporous reaches the required level a phosphorous level indicating probe carried on the member 47 emits a signal causing the piston 17 to be lowered, stopping the flow of phosphorous, and the carriage 39 to be raised by cylinders 40 until it contacts a limit switch causing further actuation of the cylinder 37 and/or rotation of the frame 36 to position the nozzle for filling the next drum. The filling nozzle may also be used in the drumfilling installation described and claimed in copending Specification 1,374,313.

Title: A device for comparing digital data represented by electric signals
IPC: G06F7/02
Filed: 1955-12-21
Abstract: 816,436. Digital electric calculating-apparatus. INTERNATIONAL BUSINESS MACHINES CORPORATION. Dec. 21, 1955 [Dec. 31, 1954], No. 36614/55. Class 106 (1). In a device for comparing two numbers A and B registered on triggers V1, Figs. 1D, 1H (only the 4 and 8 bits of the units order denomination being shown) each pair of corresponding stages is coupled to a gate V5, Fig. 1D, arranged to be open only when the two associated stages are registering the same bit, the gates V5 being connected in series by triodes V6, and leads W20 from the highest valued stage to the lowest valued stage, and the comparison is effected by a test pulse which, being entered at the gate V5 of the highest valued stage, ripples through the series connected gates V5 until it reaches one which is closed, signifying that the bits registered in that stage are not identical, whereupon the test pulse is diverted from the chain of gates V5 to a double gate V9 in the stage where the inequality has occurred, and then depending upon whether the number A is larger or smaller than the number B it passes through either the right-hand or the left-hand half respectively of gate V9 to set on one of triggers V12 or V11, Fig. 1I and give a visual indication of whether the number A is larger or smaller than the number B on one of two neon lamps L2, L3. If the numbers A and B are equal the test pulse passes through all the gates V5 and sets on a trigger V10, Fig. 1I, and a lamp L1. Each trigger V1 is of the type described in Specification 722,516, [Group XL (c)], which is referred to, having inverse outputs from the collectors of two transistors T2, T3, which are cross-coupled by leads W1] 1 and W12 to the outputs of the associated stage of the other register, and to triodes V2, V4, Fig. 1D, for controlling the gate V5. When two associated triggers V1 register different bits, one of tubes V2, V4 conducts, lowering the anode potential of a double triode V3 and thus closing the gate V5. The test pulse when it reaches a gate V5, is applied via the lead W20 to the control grid thereof, and if the gate is open it passes through and via the triode V6 to the next gate V5 in the series. If the gate V5 is closed, i.e. if the anode of double triode V3 is low, one of the sides of the double gate V9 will be open, depending upon which of the two triggers V1 is on, and the test pulse will pass via a lead W16 from the control grid of the gate V5 and one side of gate V9 to the indicating unit. When the gate V5 is open both sides of the gate V9 are closed by a normally conducting triode V8. As described, each register A, B includes several decimal denominations each consisting of a decimal counter-the addition of 6 being achieved by feed back from a triode V7, Fig. 1D-but the registers could be pure binary registers, and in a second embodiment (Figs. 2A-2H., not shown) conventional Eccles-Jordon triggers are employed. The comparator could be used in a record card collating machine, the indicating triggers being used to control appropriate switches.

Abstract: 1496138 Detecting strip moving along a grid BRITISH STEEL CORP and UNIVERSITY OF SHEFFIELD 20 Aug 1975 [23 Aug 1974] 37191/74 Heading G1N [Also in Division H4] A method of doing this comprises directing a beam of electromagnetic radiation on to the grid bars, detecting the level A of the return signal, and producing an output signal when the return signal falls below a fraction of A, due to the strip presence. The strip is moved by rollers 10. Antenna 15 directs micro-wave radiation from source 16 through window 14 on to bars 12 of grid 11 over its full width. The reflected radiation is focused on antenna 17 by unequal spacing of bars 12 such that the increased path length for each successive bar is an integral number of half wavelengths. The scattering surface of each bar is normal to the incident radiation. Micro-wave detector 19 gives with amplifier 20 an amplified D.C. signal V 0  which is fed to peak detector 21 and comparator 22, where it is compared with a fraction α of the peak signal. If it drops to V 1 , which is less than αV 0 , the output signal from comparator 22 switches on a strip coiler. The micro-wave wavelength of about 8 GHz is related to the bar spacings. The method is used to detect the leading end of hot strip in a steel strip rolling mill.

Title: Cooling of vapour phase oxidation products
Inventor: ANCRUM ROBERT WILLIAM
IPC: C01G49/06
Filed: 1957-11-29
Abstract: In the production of oxides of metals or silicon by the vapour-phase oxidation of the corresponding chlorides, in the absence of gases which would burn to form water, the hot products of the oxidation are quenched <PICT:0849140/III/1> with water thereby cooling them so rapidly that substantially no hydrochloric acid is formed by reaction between the chlorine and the water.  Cooling is normally effected to a temperature below 200 DEG C. and preferably below 100 DEG C.  The oxides may be recovered as an aqueous slurry by passing the cooled gaseous suspension to a scrubbing tower where it is washed with a further quantity of water.  Both quenching and scrubbing operations may be effected by a recycled aqueous slurry of the oxide.  As shown in the Figure, titanium tetrachloride is reacted with oxygen to yield titanium oxide and chlorine together with excess oxygen, atmospheric gases and, if an auxiliary fuel is used, carbon dioxide; the oxide-bearing stream, at a temperature of 600-1200 DEG C., is passed into a spray cooling tower 1, supplied with a slurry of titanium dioxide in water at 85 DEG C. by pump P1.  A small proportion of the oxide product is slurried in water and flows to a recirculation tank 5, whilst the cool gaseous suspension is passed to a scrubbing tower 2, also fed with oxide slurry from tank 5.  The whole of the titanium oxide product is removed in tower 2 as an aqueous slurry and passed to tank 5, whilst the cool gases, now at about 85 DEG C. and saturated with water vapour are passed to a gas-cooling tower 3 where they travel counter current to cold water thereby reducing their temperatures at 25 DEG C.  The so-cooled gases are exhausted and treated for the recovery of chlorine.  The aqueous pigment slurry obtained in tank 5 is passed to a thickener 7 and from thence to recovery processes.  The recirculated slurry is normally of a concentration up to 250 gms/litre of titanium dioxide.
